Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical navigation systems face challenges as the positioning members on the patient's affected area can obstruct the surgeon or assistants during operations, leading to potential inaccuracies and surgery failures.
Innovation Solution
A surgical navigation system comprising a positioning device with an auxiliary positioning assembly that includes a wearing member, a connecting seat, and an optics positioning assembly, allowing for the positioning of auxiliary marks on the patient's affected area without obstructing the surgical site, using magnetic units for secure attachment and a rotatable design to minimize interference during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning members are disposed on the patient's affected part to enable accurate positioning, then positioning accuracy is improved, but the surgical operation is hindered due to obstruction by positioning members
Solution Approach 1:
The positioning system is divided into two separate components: a positioning member that remains on the patient's affected part for accurate positioning, and an auxiliary positioning member that is detachably connected to the first positioning member. This segmentation allows the auxiliary positioning member to be removed after positioning is complete, eliminating obstruction during surgery while maintaining positioning accuracy.
Solution Approach 2:
The auxiliary positioning member is designed to be detachably connected to the positioning member, allowing it to be extracted or removed after the positioning function is fulfilled. This extraction enables the surgical field to be cleared of obstructions while the positioning member remains in place to maintain positioning accuracy throughout the procedure.
2Stability of the object's composition
If positioning members are fixed on the affected part to prevent repositioning, then positioning stability is improved, but the device complexity increases due to additional attachment mechanisms
Solution Approach 1:
The connection between the auxiliary positioning member and the positioning member is designed to be dynamic rather than fixed. The detachable connection allows the auxiliary positioning member to be easily attached and detached as needed, providing positioning stability when required while avoiding permanent fixation that would increase device complexity.
Solution Approach 2:
The auxiliary positioning member serves multiple functions: it provides additional positioning references during the procedure, can be detached to clear the surgical field, and can be reattached if needed. This multi-functionality reduces the need for complex dedicated attachment mechanisms while maintaining positioning stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively assists in accurate positioning without hindering surgical operations, enhancing the precision of surgical procedures by integrating medical images with positioning information for real-time navigation, reducing the risk of incorrect drilling or implant placement.
Implementation Method 1
The optics positioning assembly comprises a plurality of sensing units which can sense the position of the auxiliary positioning marks and the position of the hand tool positioning marks
Implementation Method 2
The connecting seat and the connecting member respectively have magnetic units, and the magnetic unit of the connecting seat is opposite to the magnetic unit of the connecting member. Further, the magnetic unit of the connecting member may be attracted to the magnetic unit of the connecting seat

AI summary
The present invention provides a surgical navigation system including a positioning device, a processing device and a display device. The positioning device includes an auxiliary positioning assembly capable of wearing or fixing around a patient's affected part and an optics positioning assembly. The optics positioning assembly can sense the position of the auxiliary positioning assembly to form a positioning information. The processing device can receive the positioning information and integrate the positioning information with a medical image to form a navigation information, so that the navigation information is displayed on the display device through a stereoscopic image or a sectional image. Therefore, the doctor can accurately perform the relevant surgical operations on the patient's affected part through the displayed information.
